Make your battery level always visible, with accurate percentage scale.

Tips:

Customize the appearance of the panel using color picker dialogs. Also you can adjust transparency and size of the panel in Sliders section.
Tons of gauges could drain your battery very quickly. Uncheck the features that you do not need. Btw, Cool Tool went to sleep and do not draw anything when your display turns off. It is for power save.
